Ist das RAM ok?

Ich tippe, daß die ATI-Grafikkarte einen Schuß hat. Wurde bei meinem MacPro bereits 3x ausgetauscht (AppleCare sei Dank). Immer nach ein paar Monaten sind die immer heißer gelaufen, dann traten die gleichen Symptome wie bei Dir auf und irgendwann ging gar nix mehr. Habe mit der APP SMS FanControl dann die Umdrehungszahl der Lüfter hochgesetzt, damit konnte ich den Totalschaden noch etwas hinauszögern... wenn Du noch Garantie hast, dann unbedingt checken lassen, evtl. kannst Du eine Karte von ATI auf Kulanz bekommen bzw. aushandeln, denn die Problematik scheint dort bekannt zu sein (wird nur nicht propagiert).
Viel Glück.
